MAGNETS COULD HELP TO REDUCE ALZHEIMER'S PAIN

Using a magnetic coil to stimulate the parts of the brain involved in memory and learning could help delay the progression of Alzheimer's disease, according to researchers.

The researchers believe that used early in the course of the disease, it would give patients precious extra months of independent living, as well as time with their loved ones before their physical and mental health deteriorates.

The technology, known as trans-cranial magnetic stimulation , had already been tried on Alzheimer's patients, with promising results.

In a new test being conducted in Manchester, six patients in the early stages of the disease will be having a magnetic coil held over their scalp while they answer questions, identify shapes and solve puzzles.

It is hoped that as the magnetic field passes into key brain areas it will strengthen vital connections between cells.

In tests on mice, the technique also boosted the growth of cells in the hippocampus, the brain's memory hub and one of the first areas to be destroyed by Alzheimer's.

Brain scans at Manchester University will aim to find out more about how it works.

In a small-scale trial in Israel, it proved to be both safe and effective, with significant improvements in some, but not all, tests of memory.

The results showed marked reversal of disease progression with patients improving to a state comparable to two years before treatment initiation, according the the researches.

"Trials also indicated that improvement is maintained for at least six months post-treatment," it added.

"We are not offering a cure but a way to help patients stay independent and have a better quality of life for longer," according to researchers. 

Indian researchers develop nanosystem to kill cancer cells

Work by a team of Indian researchers, who have developed a 

novel multi-component magnetic nano system that could image

 and kill cancer cells.




The design of nano system is bridged on grapheme - a carbon 

allotrope, which could specifically target cancer cells, and 

deliver cargo of anti-cancer drugs and imaging agent.

The challenge was to design a multicomponent nano system 

and simultaneously which would be bio-compatible for cancer 

cells.

This multicomponent nano system acts as a stronger cellular 

probe in imaging cancer cells, which is a powerful diagnostic 

tool. It can also be directed to target cancer cells and cancer 

tumour using external magnetic field.
